2 Claims.

This invention is directed to a novel construction of extension table.With the present invention the table when not in use maybe retracted tooccupy relatively small space, no more than that generally occupied byan ordinary desk,

but may be extended and enlarged to substantially any desired degreewithin the limits of the slide extensions used, so as to produce a tablehaving a horizontal top of desired size, which after it has been usedmay again be retracted to its initial small size.

The invention may be fully understood from the following description,taken in connection with the accompanying drawings, in which:

Fig. 1 is a plan View of the table as it is undergoing the first stepsof extension.

Fig. 2 is a transverse section through the extended table substantiallyon the plane of line 22 of Fig. 1.

Fig. 3 is a view similar to Fig. 2, showing the foldable top memberunfolded and lying in the same plane with the fixed top section of thetable.

Fig. 4 is a vertical section through the upper part of the table in itsretracted condition. I

Fig. 5 is a similar. section with the table in extended position withoutextension leaves or fillers therein.

Fig. 6 is a view similar to Fig. 5 but with the table further extendedand using filler leaves, and

Fig. '7 is a fragmentary vertical section similar to Fig. 4,illustrating the releasable lock which holds the parts in its retractedposition.

Like reference characters refer to like parts throughout the differentfigures of the drawings.

member I has vertical supporting posts 2 underneath the two outercorners thereof, between which is a depending apron 3, while from eachpost an end member 4 extends underneath and adjacent the ends of the topmember or section 'I, as shown in dotted outline in Fig. 1. Twoextension slides are used and one of the end members 5 of each of theslides is permanently secured to and underneath the top member I. Be-

tween the other end members 6 of the two series of slides are aplurality of intermediate slides I,

as shown, such extension slides being of a conventional and well-knowncharacter.

Associated with the outer slide members 6 and connected thereto are twoadditional posts 8 spaced apart from each other like the posts 2,

and having between them an apron 9 similar to the apron 3, whileextending therefrom in planes at right angles to the apron 9 are endmembers I0, lying along the outer sides of the end slides In theconstruction shown, a horizontal top 6 and secured thereto. A board IIextends between and underneath the end slides 6 and is secured at itsends thereto, having its outer edge connected to the inner side of theapron 9 and e at its inner edge being recessed to provide an elon- 5gated recess as shown at I2. It is evident that the posts 8 andconnected partsmay be moved inwardly so that the upper ends of the postswill come underneath the other corners of the fixed top member I, andwith the end members II! 10 coming inside the end members 4, in whichposition the table Will have a top area consisting only of the member I.v

On the upper side of the board I I and one side of the middle thereof ablock I3 is permanently 151 secured, which, adjacent its inner end,carries a supporting bracket l4 through which a rod I5 passes. The rodat its outer end is flattened and bent down and permanently secured tothe block I3, the rod in the retracted position of the tablezo extendingunderneath the top member I, as shown in Fig. 4. One section I6 of afoldable top member is mounted on the rod I5 by means of'spaced bracketsI? connected to the section It and through which rod I5 freely passes.outer end of the rod I5 is up-set to make stops I8 whereby the bracketsI'I maynot disengage from the rod. However, it is evident that thebrackets Il may be moved along. the length of the rod within the limitsprescribed by the two stops I4 30 and I8 against which the oppositebrackets I! will come when moved in opposite directions. A second memberI9 of the same size as the part It is hinged at 20 to one edge thereofand in the folded position lies underneath theupper part:35

I6 and at one corner bears upon the upper side of the board I II beyondone end of the recess I2 therein.

By turning the folded top section consisting of the two parts I6 and I9in a clockwise dimetion (Fig. 2) about the axis of the rod I5, the uppersection I6 will be extended outwardly, as shown in Fig. '3 and pass overthe members 6 and I of one of the slides and the adjacent end memberIll, and the then uppermost section 19 may 5 has been unfolded andbrought to the position shown in Fig. 3, it is moved on. the rod [5toward and over the upper edge of the apron 9 until the stops 2| comeagainst the inner side of said apron, whereupon the foldable top sectionis properly located with respect to the posts 8. Thereafter, if thetable is to be no further enlarged, the slides are retracted until theadjacent edges of the partslS and I9 and of the top member I are broughttogether as in Fig. 5. In the movement of the foldable top memberoutward to bring the stops 2| against the apron 9, the section [9 iscarried upwardly and over the inclined leg of an angle bracket 22 (Fig.7) secured at the inner side and near the upper edge of the apron 9,thus insuring that the outer edges of the parts l6 and [9 will not abutagainst the inner upper edge portions of the apron 9.

When the table is retracted as in Fig. 4, it is er end being connectedwith a manual release member 25 of spring material which is fully shownand described in application Serial No. 259,941 filed March 6, 1939. Akeeper block 26 has a recess in its under side and has a cam edgeunderneath which the upper end of the pin 25 rides until-the recessis'reached, the spring member 25 yielding and when the recess is reachedmoving the upper end of the pin 25 into said recess. The pin may bereleased by manual operation of the member 25 when an extension of thetable is contemplated. There is also associated with the table afoldable center supporting leg of the same construction shown in mypending application, Serial No. 206,775, filed May 9, 1938. Thehorizontal board 21 extendsbetween and is secured to the under side ofslides I of the two series of slides and said board is slotted from oneend for a greater portion of its length, with a ioldable top sectionconsisting of the parts l6 and I9, filler leaves may be located whichrest upon the upper edges of the slides I.

The constructionof table described is of a very practical andserviceable character. The extension of the table to either the positionshown in Fig. 5 orthat in Fig. 6 is quickly and easily accomplished. Thereturn of the table to the retracted position in which it occupies muchless space is easily and readily done. The invention is one of greatpractical utility.

The claims a pended hereto define the invention, which is to beconsidered comprehensive of all forms of structure coming within theirscope.

I claim:

1'. In a table, a horizontal top section, supporting legs connectedtherewith and extending downwardly substantially at its outer corners,extensible slides comprising end slide members and intermediate slidemembers, one of the end slide members of each of said extensible slidesbeing connected to the under side of said top section, additional legsconnectedto the outer ends of the other end slide members and movabletherewith, an apron located in a vertical plane between and connected atits ends to the upper portions of the legs, a horizontal board connectedat one edge to said apron and extending inwardly therefrom, having itsends secured to and at the lower sides of said other end slide members,said board adjacent its inner edge having a relatively long recesstherein, a horizontal rod connected and sup-ported at one end on saidboard and extending inwardly away from the apron, a foldable top sectioncomprising two sub stantially equal parts hingedly connected end to end,and spaced brackets secured at one side of one of said parts of thefoldable top section through which the rod loosely passes, said foldabletop section in folded condition being adapted to be turned about theaxis of said rod through the recessed portion of said board throughsubstantially 180 and thereafter unfolded to bring the two parts intoalinement and'into the same horizontal plane with the 'first topsection.
